7018.20 Subheading
Section XIII — Articles of stone, plaster, cement, asbestos, mica or similar materials; ceramic products; glass and glassware

About HS Code 701820

This highly specialized category covers minute glass spheres, each with a diameter not exceeding 1 millimeter. These microspheres possess unique properties such as high reflectivity, low density, chemical inertness, and excellent compressive strength, making them invaluable across a diverse range of industrial applications. They are critical components in sectors requiring precision, durability, and specific optical or physical characteristics. Key importers include manufacturers in the automotive (e.g., road markings), aerospace, medical (e.g., diagnostics), construction (e.g., lightweight fillers), and coatings industries. Exporters are typically specialized chemical or glass processing companies with advanced manufacturing capabilities. Critical aspects for trade include precise size distribution, surface treatment, refractive index, and material composition, which dictate their suitability for specific high-performance uses.
